Tuesday, January 12, 2010, 8:30 AM: After last week’s hike to $2.79, prices haven’t moved much either at the wholesale or retail level. I’m going to make use of the stock market/gas price correlation of the last few years, and with stocks looking to drop today (and, I’m guessing, the rest of the week), wholesale gas prices will too, and so will retail prices. So I predict lower prices through the weekend. In other news, I continue to track diesel prices, which is kind of boring so far. At the Speedway on Lake Michigan Drive, the price was $2.85 from mid-October until the last few days. Now it is $2.95. — Ed Aboufadel
